Your dress(es) look really good! Nice colour, nice print, nice fit.
I hadn’t thought of making an under- and overdress combination before but that would be a comfy and warm extra layer in winter. And you can even mix and match them for even more variety.
An over and under dress is really cool! I have not seen that. Sometimes I’ll pair leggings and a shrug with my dresses, but I hadn’t thought of this.
I love a poof sleeve and you matched the belt perfectly! Everything looks great together. Awesome!
